This paper reports several studies of chess expertise in children who play competitive chess. The first study examines (1) the relationship between experience and skill among 113 school-age children (grades 1 through 12); and (2) the relationship between chess skill and scores on various spatial and logical abilities tests among the top 15 players. Improvement in skill is related to experience, and chess players score higher than average on the Raven's Progressive Matrices. Also, scores on a chess-specific test, the Knight's Tour, correlate with scores on the Raven's. The second study reports three experiments with 59 Ss involving chess-specific tasks in memory, perception, and similarity judgements. The first two experiments replicated and extended Chase and Simon (1973). The third experiment, which asked Ss to judge similarities of chess positions, demonstrated that similarity judgements become more global and abstract with increased skill. The final section describes qualitatively how children's chess expertise compares to that of adults. Drawing upon Anderson (1985), we focus on some distinctive features of children's chess play and on some successful techniques in coaching young players. 相似文献

A new method is introduced for assessing children's component selection—i.e., the disposition to attend to a single feature of multifaceted stimuli. Eight-year-old children were found to exercise component selection to a lesser degree than 4-year-olds; while children at both age levels attended primarily to one stimulus component (shape), the older children showed a moderate amount of attention to a secondary redundant feature (color) as well. However, a comparable age difference in attention deployment was not observed when a single stimulus dimension (shape) was “relevant” in two variant tasks. These results imply a developmentally increasing ability to distinguish between conditions in which attending to redundant stimulus information can and cannot be useful. That this ability undergoes little further development beyond age 8 was suggested in a second experiment with 8- and 12-year-olds in which the three tasks produced relatively similar developmental trends in performance. 相似文献

Almost every formal model of explanation thus far proposed has been demonstrated to be faulty. In this paper, a new model, proposed by Raimo Tuomela, is also demonstrated to be faulty. In particular, one condition of the model is shown to be too restrictive, and another condition of the model is shown to be too permissive.This research was supported by a grant from the Killam Foundation, administered by the Canada Council. 相似文献

Four groups of rats were trained to run an alleyway with one trial per day. Two groups were always deprived when trained while the other two received a partial deprivation schedule. One group of each pair received a continuous reward in the goal box while the other received partial reward. A partial reinforcement effect was found during extinction. The partially deprived groups also showed persistence in extinction. This result extends parallels between the effects of satiation and nonreward upon behaviour. 相似文献

Using both partners as informants and three interdependence measures (contact, aid, and attachment) as criterion variables, we address the assumption that women's orientation to and dependence on other generations differ because of unique roles. In 135 pairs of student women and their mothers and 119 pairs of middle-aged women and their mothers, we ask how a woman's role position interacts with her partner's role position in regard to interdependence. Both dyadic and individual role combinations are examined. In younger pairs, we examine the combination of daughter's marital status and both mother's launching and work statuses; in older pairs, we examine the combination of mother's marital status and both daughter's launching and marital statuses. Regression analyses demonstrate that, except for younger pairs where married daughters and their mothers are less interdependent than single daughters and their mothers, interdependence is remarkably unrelated to role positions, singly or in combination. Results suggest normative pressures toward new conjugal bonds and stability in women's family roles. 相似文献
